The possibility of increasing the efficiency of utilization of spent motor oils as the dispersion medium of lubricating greases has been explored. It has been established that the removal of resins, asphaltenes, carbenes, and carboids from used mineral and synthetic motor oils makes it possible to obtain a base stock close to commercial base oils in the main characteristics. It has been proposed to use carbamide or monoethanolamine in a mixture with isopropanol. It has been found that more than 90% of the contaminants are removed from used engine oils by refining according to the methods proposed. The re-refined oils have a high margin of performance. The composition of Litol-24 and Solidol Zh grease analogues based on refined waste motor oils has been determined. The corrosion-preventing, adhesion, and strength properties of the lubricant compositions are considered. The results of bench testing of lubricant compositions in rolling bearings, which confirm their high performance properties, are presented.
